The aim of this paper is to investigate and understand the effect of high-school friends on years of schooling. We develop a simple network model where students first choose their friends and then decide how much effort they put in education. The empirical salience of the model is tested using...

We analyse the impact on schooling outcomes of growing up in a family headed by a single mother. Growing up in a non-intact family in Germany is associated with worse outcomes in models that do not control for possible correlations between common unobserved determinants of family structure and...

The determinants of the dramatically rising expenditures on health care in general, and on hospital care in particular, have been of prior concern to policy and to research. Using a rich panel data set this paper contributes to this literature by investigating factors determining the demand for...

For given observable parental characteristics, children with divorced or separated parents tend to perform less well at school than children living with their two parents. This result has been used to argue that softening divorce legislation might be bad for children. This might, however, just...

In this paper we focus on the implications of consumer heterogeneity for whether competition will improve outcomes in health care markets. We show that competition generally favours the majority group as higher quality for the majority is an effective way to increase the quality signal and...

Many literatures investigate the causal impact of income on economic outcomes, for example in the context of intergenerational transmission or well-being and health. Some studies have proposed to use employer wage differentials and in particular industry affiliation as an instrument for income....

In a model where patients face budget constraints that make some treatments unaffordable, we ask which treatments should be covered by universal basic insurance and which by private voluntary insurance. We argue that both cost effectiveness and prevalence are important if the government wants to...

We develop a new methodology to compute differences in the expected longevity of individuals who are in different socioeconomic groups at age 50. We deal with the two main problems associated with the standard use of life expectancy: that people's socioeconomic characteristics evolve over the...

We study the effects of a conditional cash transfers program on school enrollment and performance in Mexico. We provide a theoretical framework for analyzing the dynamic educational process including the endogeneity and uncertainty of performance at school (passing grades) and the effect of a...

The speed at which immigrants assimilate is the subject of debate. Human capital formation plays a major role in this discussion. This paper compares the educational attainment of second generation immigrants to those of natives in the same age cohort. Evidence using a large German data set...
